IMPORTANT INSTALLATION INFORMATION
• Victaulic
®
VicFlex
™
products shall be installed according to
current, applicable National Fire Protection Association (NFPA
13, 13D, 13R, etc.) standards or equivalent standards and in
accordance with applicable building and fire codes. Victaulic
®
VicFlex
™
products are intended to be installed in wet, dry, or
preaction actuated systems. Deviations from these standards or
alterations to Victaulic
®
VicFlex
™
products or sprinklers will void
any Victaulic warranty and will impact system integrity. Installations
shall meet the provisions of the local authority having jurisdiction
and local codes, as applicable, and shall comply with all design
specifications.
• Drop ceiling construction shall meet the requirements of ASTM
C635 and shall be installed in accordance with ASTM C636.
• Victaulic
®
VicFlex
™
Sprinkler Fittings and Style AB1, AB2, or AB10
Brackets shall not be intermixed with other manufacturer’s flexible
sprinkler products.
•
When using recessed sprinklers, the standard long elbow reducer
is recommended.
•
Refer to the specific Victaulic product publication for
applications and listing information. In addition, when installing
Victaulic FireLock
®
Automatic Sprinklers with Victaulic
®
VicFlex
™
Sprinkler Fittings, refer to the I-40 Installation and
Maintenance Instructions for details on sprinkler installation
requirements. Product publications and installation instructions
can be downloaded at victaulic.com.
•
Size the piping system to meet or exceed the minimum required
flow rate for the sprinkler system.
•
Per NFPA requirements, flush the system to remove foreign
material. Continue to flush the system until water runs clear.
•
DO NOT
install sprinkler system piping through heating ducts.
•
DO NOT
connect sprinkler system piping to domestic hot water
systems.
•
DO NOT
allow electrical wiring or other cabling to be hung or
wrapped around the sprinkler piping system.
•
DO NOT
install sprinklers and sprinkler fittings where ambient
conditions may fall below or exceed the maximum listed or
approved temperature ratings.
•
The flexible hose shall not be bent or fluctuated up-and-down or
side-to-side when pressurized.
•
Victaulic VicFlex flexible hoses may be painted or coated, provided
that the paint or coating is compatible with stainless steel material.
Care shall be taken to ensure that the sprinkler and associated
components are not painted.
•
Flexible hose and fittings have limited flexibility* and are
intended only to be installed with bends not less than their
respective minimum bend radii. DO NOT install flexible hose in
a straight configuration.
•
Protect wet piping systems from freezing temperatures.
•
If construction is altered, the building owner or their representative
is responsible for referencing applicable standards to determine if
additional sprinklers or other system adjustments are required.
•
The building owner or their representative is responsible for
maintaining the fire protection system in proper operating
condition.
•
After installation is complete, the entire sprinkler system shall be
tested in accordance with applicable standards (NFPA 13, NFPA
25, etc.) that describe the care and maintenance of sprinkler
systems. In addition, the authority having jurisdiction may have
additional maintenance, testing, and inspection requirements that
shall be followed.
NOTE:
A successful test is not a substitute for
proper system installation and maintenance.
WARNING
• Relocation of Victaulic
